How you do consider for the price to be low? There's no such thing about low price or bottom price because everything could really be in random or cant be known on what would be the sweet spot.
If you do love to deal with established coins then bitcoin would be the key but dont expect that its value would rise up really that fast compared into low cap coins around.
Invest on what you can afford to lose and dont mind about profiting in a short time.
The good thing about investing or putting your money in an established cryptocurrency like bitcoin, ethereum, binance and other top crypto in the market is that we can assure that the price may still go up no matter how long it takes because they are already established. The crypto market is so volatile and that should be know by anyone who would want to join in the cryptocurrency because if you don't know about it then you probably taking the riskiest journey of your life, we are not only talking about the amount we can afford to lose but also the amount of knowledge you are with in dealing with cryptocurrency.
